subroutine inform(progid)

  !! Routine to obtain information about the program being executed
  !! author: P J Knight, CCFE, Culham Science Centre
  !! progid(0:10) : output string array : Strings containing useful info
  !! This subroutine uses system calls to identify the user, date,
  !! machine etc. for the present run, and stores the information
  !! in a character string array.
  !!   !
  ! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  use constants, only: nout
  implicit none

  !  Arguments
  character(len=110), dimension(0:10) :: progid

  !  Local variables
  character(len=10) :: progname
  character(len=98) :: executable
  character(len=*), parameter :: progver = &  !  Beware: keep exactly same format...
       '3.1.0   Release Date :: 2024-03-21'
  character(len = 50) :: dt_time
  character(len=72), dimension(10) :: id

  ! !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  !  Program name
  progname = 'PROCESS'
  call get_command_argument(0, executable)
  call get_DDMonYYTimeZone(dt_time)
  id(1) = trim(dt_time) ! values(3)//"/"// values(2)//"/"// values(1)  ! 5 6 7!date
  call getlog(id(2))    ! Get user ID
  call hostnm(id(3))    ! Get host name
  call getcwd(id(4))    ! Get current working directory

  !  Annotate information and store in PROGID character array
  !  for use in other program units via the routine argument

  progid(1) = '  Program : ' // executable
  progid(2) = '  Version : ' // progver
  progid(3) = 'Date/time : ' // id(1)
  progid(4) = '     User : ' // id(2)
  progid(5) = ' Computer : ' // id(3)
  progid(6) = 'Directory : ' // id(4)

  !  Summarise most useful data, and store in progid(0)
  progid(0) = trim(progname) // ' ' // trim(progver(:7)) // &
       ' : Run on ' // trim(id(1)) // ' by ' // trim(id(3))
